1. A method for operating a mobile station having an output power limit, the method comprising the steps of:

  • establishing a wireless data communication from a transmitter of the mobile station to a receiver of the base station at a predetermined data rate simultaneously through at least one channel;

    receiving a command from the base station to increase a transmission power of the mobile station transmitter;

    determining in the mobile station if the increased transmission power on at least one data channel will exceed the output power limit of the mobile station;

    if so, reducing the data rate by disabling data transmission through at least one of the at least one data channel;

    increasing the transmission power on any of the at least one data channel that carry data transmissions after the step of reducing the data rate is performed;

    receiving a command from the base station to decrease the transmission power of the mobile station;

    determining in the mobile station if the decreased transmission power, assuming that a disabled data channel were once more enabled, will not exceed the output power limit of the mobile station;

    if so, increasing the data rate by enabling data transmission through at least one previously disabled data channel; and

    decreasing the transmission power on any of the at least one data channel that carry data transmissions after the step of increasing the data rate is performed.
